Halogen-doped phosphorous nanoparticles and a manufacturing method thereof are provided. The manufacturing method includes a mixing process and a centrifugation or filtration process. The mixing process has the step of mixing a precursor with a reducing agent solution to form a mixed solution, the precursor is a halogen-based phosphide. Then, the mixed solution is centrifuged or filtrated to obtain the halogen-doped phosphorous nanoparticles.

Halogen doped phosphorus nanoparticles and manufacturing method thereof

A method of inducing autophagy in a cell is achieved by contacting the cell with graphene oxide (GO) in an amount effective to induce autophagy in the cell, wherein the cell expresses at least one of TLR-4 (Toll-like receptor 4) and TLR-9 (Toll-like receptor 9). Differences between autophagy triggered by GO and other conventional agonists such as rapamycin have been observed. GO may activate autophagy in some cells that may not be triggered by rapamycin. The cell reveals no apparent apoptosis after treatment of the graphene oxide. A method of activating a Toll-like receptor in a cell is also herein provided.
